As representações do ofício de professor : uma investigação empírica

Este trabalho de investigação, de natureza empírica, procurou conhecer e reflectir sobre as representações do ofício de Professor para os entrevistados, fossem eles docentes ou não docentes. As diversas questões que permeiam o debate sobre a formação docente e a qualidade do ensino são destacadas pelos profissionais da educação e por profissionais de áreas completamente distintas. O papel do Professor é o foco central das entrevistas e a profissão docente, apesar das dificuldades apontadas, é reconhecida e exaltada como uma profissão de fundamental importância para quem almeja a construção de um mundo melhor e de uma sociedade mais justa. A metodologia de pesquisa utilizada é, quanto ao fim, descritiva e, em relação aos meios de investigação, bibliográfica e de pesquisa de campo. Neste trabalho, foi utilizado o método de análise de conteúdo baseado em BARDIN. Este método aparece como um conjunto de técnicas de análise das comunicações que utiliza procedimentos sistemáticos e objectivos de descrição do conteúdo das mensagens. As respostas dos entrevistados foram categorizadas segundo as regras de análise de categorização das informações por homogeneidade, exaustividade, exclusividade, objectividade e adequação ou pertinência. Seguindo-se esta metodologia e com o objectivo assumido de contribuir para o debate acerca da formação docente, foi realizado o presente estudo de investigação, que agora se apresenta. /ABSTRACT: This research, empirical, sought to know and reflect on the representations of the Professor's profession on respondents, teachers and non teachers.

On The Use of Genetic Algorithms for Parameter Identification in Anaerobic Digestion Modelling

Anaerobic digestion (AD) of wastewater is a very interesting option for waste valorization, energy production and environment protection. It is a complex, naturally occurring process that can take place inside bioreactors. The capability of predicting the operation of such bioreactors is important to optimize the design and the operation conditions of the reactors, which, in part, justifies the numerous AD models presently available. The existing AD models are not universal, have to be inferred from prior knowledge and rely on existing experimental data. Among the tasks involved in the process of developing a dynamical model for AD, the estimation of parameters is one of the most challenging. This paper presents the identifiability analysis of a nonlinear dynamical model for a batch reactor. Particular attention is given to the structural identifiability of the model, which considers the uniqueness of the estimated parameters. To perform this analysis, the GenSSI toolbox was used. The estimation of the model parameters is achieved with genetic algorithms (GA) which have already been used in the context of AD modelling, although not commonly. The paper discusses its advantages and disadvantages.

The application of symphytosociology in landscape architecture in the Western Mediterranean

This essay addresses the application of indigenous plants in Landscape Architecture projects, based on studies carried out in the field of phytosociology and sinphytosociology. Through this knowledge, it is possible to increase and improve the use of indigenous plants in Projects, aiming at the preservation of biodiversity. Thus, to better understand the western Mediterranean territory, we present a brief biophysical characterization, in which we point out the main factors which contribute to the ground coverage’s distribution in the landscape, namely, concerning climate (oceanity, ombroclimate and thermoclimate) and substrate (geology and lithology). In view of the high level of uniqueness of the identified conditions, a synthesis of the potential main existing climatophilous woods is carried out, regarding sinphytosocialogical class/order, furthermore, pointing out, the main serial stages, their vegetation bioindicators and the ecological peculiarities of each stage (regressive or progressive). Therefore, based on the study area, we point out the vegetation bioindicator’s value as a work tool during analysis, thus allowing us to understand the existing edaphoclimatic conditions, as well as to elaborate a quick diagnosis of each potential climatophilous vegetation series. Moreover, based on the main stages of substitution, it is also possible to identify the presence of endemic plants, or under protection status, and finally, the conservation state of the study area. Further ahead, in project proposal phase, based on information gathered previously, we point out the possibility of elaborating a list of plants correctly adapted to the existing mesologicall conditions. Thus, within each serial stage, the necessary ecological conditions for a correct adaption of the vegetation material are referred, therefore, avoiding possible limiting factors to their development, such as precipitation, soil erosion, light availability, salinity, among many others. Lastly, some considerations are made about the main ideas that should be remembered throughout this essay, namely, regarding the importance of the use of sinphytosociology’s knowledge as an analysis tool, as well as of high interest for the elaboration of proposals which aim at the floristic heritage’s conservation and the landscape’s scenic quality. Ce travail traite de l`application de plantes autochtones dans des projets d`Architecture Paysagiste ayant pour base des études réalisées dans le cadre de la phytosociologie et Symphytosociologie. À travers ces connaissances, il est possible d`incrémenter et améliorer l`utilisation de plantes autochtones dans les Projets basés sur la conservation de la biodiversité. Ainsi, afin de mieux comprendre le territorie de la méditérrannée occidentale, on présente une brève caractérisation biophysique, dans laquelle nous soulignons les principaux facteurs qui contribuent à la répartition de la végétation dans le paysage, notamment au niveau climatique (l`océanité, ombrothermique et thermoclimatique) et du substrat (géologie et lithologie). Face aux conditions, identifiées ci-dessus, élévées en originalité, il est utile d`élaborer une synthèse des principaux bois potentiels climatophiles existants au niveau de la classe/ordre symphitosociologique, en soulignant également les principales étapes de série, leurs bioindicateurs végétaux et aux particularités écologiques de chaque étape (régressive ou progressive). Ainsi, sur la base de l`interprétation de la zone d`étude, le bioindicateur végétal se distingue comme un outil de travail durant l`analyse, permettant de cette façon comprendre les conditions édapho-climatiques existantes, ainsi comme élaborer un rapide diagnostic de chaque série de végétation potentielle climatophile. En outre, sur la base des principales étapes de remplacement, il est également possible d`identifier la présence de plantes endémiques, ou avec un statut de protection et enfin l`état de conservation de la zone d`étude. Déjà au stade de proposition du projet, basée sur l`information recueillie précédemment, il y a la possibilité d`établir une liste de plantes bien adaptées aux conditions mésologiques. Ainsi, dans chaque étape de série, les conditions écologiques nécessaires à une bonne adaptation de la matière végétale sont référées, évitant ainsi des facteurs limitant à son développement, tels que les précipitations, l`érosion des soís, disponibilité de la lumière, de la salinité, parmi beaucoup d`autres. Et enfin, quelques considérations se tissent sur les principales idées à retenir tout au long du travail, notamment l`importance d`utiliser la connaissance de la symphytosociologie comme un outil d`analyse d`un grand intérêt pour la développement de propositions pour la conservation du patrimoine floristique et la qualité pittoresque du paysage.

Understanding the Coach-Coachee-Client relationship: A conceptual framework for executive coaching

Objectives: There is a need for a more comprehensive understanding of how coaching processes psychologically operate. This paper presents the findings from a study aimed to characterise the coaching process experience and to identify how specific experiences contribute to coaching outcomes. Design: A qualitative design was adopted. Data was analysed by Interpretative Phenomenological Analysis (Smith, 2008). Method: Data was collected from 10 participants, this included coaches (N=4), coachees (N=5) and one commissioner, three times along the coaching process. A total of 30 interviews were undertaken. Findings: Coaching outcomes can be generated by three essential mechanisms: Projection of Future Self; Perspectivation of Present Self; and Confirmation of Past/Present Self. Each mechanism’s name represents a particular effect on coachee’s self and may evolve diverse coaching behaviours. Although they all can be actively managed to generate sustainability of outcomes, each mechanism tends to contribute differently to that sustainability. Conclusion: The study provides a comprehensive understanding of the different methodological and experiential ingredients of the coaching process and its implications. While most coaching research is focused on identifying coaching results based on a retrospective analysis, this is one of the first studies accompanying longitudinally the coaching process and capturing an integrative understanding of its dynamics. Moreover, the study provides evidence of how coaching can differently deliver sustainable outcomes and be used as a valuable developmental tool in organisations. The study contributes to our understanding of theory building and raises questions for further research on the uniqueness of coaching interventions.

Urban Identity and tourism:different looks, one single place

‘Urban identity’ is high on the policy agenda and pervades the discourse of the planning community on the value of historical city centres. Unfortunately, there seems to be, until today, no proposal in scholarly literature of any unified conceptual framework or any tools to make identity operational. ‘Tourism’ takes advantage of this process, by seeking the qualities of the place, its authenticity and its perceived uniqueness that is grounded on the physical features as well as on the presence of local communities – their way of living and investing in the place. The interdependence between identity as perceived by tourists (external observer) and the identity of the residents rooted in the relationship with the place (in-group) are key to addressing the identity of historic urban areas. These issues are addressed in the context of the growing attractiveness of Lisbon, Portugal, using a historic neighbourhood as a case study. The findings, which are on a set of interviews with different groups of users, showed the points of convergence and divergence between the different groups’ views of the neighbourhood’s identity. This actor-oriented approach is pivotal to understanding the process and to produce knowledge for informed action.

Climatic groups in Ibero-America viticulture compared to worldwide wine producer regions.

The wine production is an important activity in many Ibero-American countries. The wine producer regions of these countries configure a large use of different climate types and viticultural climates. In a vitivinicultural zoning project of CYTED (Ibero-American Program for Science, Technology and Development), a viticultural climatic characterization was done in this macro viticultural region. The project have assembled a climatic database that characterizes the viticultural regions, including relevant variables for viticulture: air temperature (mean, maximum, and minimum), precipitation, relative humidity, solar radiation, number of sunshine hours, wind speed, and evapotranspiration. Using indices of the Geoviticulture MCC System (HI, CI and DI), more than 70 viticultural regions in different countries (Argentina, Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal and Uruguay) were characterized according to its viticultural climatic. The results, which will be integrated to the worldwide database of the MCC System, showed that the Ibero-American viticulture is placed in a wide range of climatic groups of the wine producing regions around the world. This article presents the climatic groups found in Ibero-America, identifying also some new climatic groups not yet found in other regions of the world. This work also identifies some climatic groups not found in Ibero-America viticulture. The research has also highlighted viticultural areas characterized by climates with ?intra-annual climatic variability?, with the potential to produce more than one growing cycle per year. The results allow to conclude that the wide variability and climatic diversity present in Ibero-America may be one of the reasons to explain the diversity in terms of wine types, sensorial characteristics, typicity and uniqueness of wines produced on this macro-region.

Funzionalizzazione e unitarietà della vicenda contrattuale negli appalti pubblici

La tesi intende analizzare l’unitarietà della vicenda contrattuale dell’appalto pubblico nell’ottica del superamento della tradizionale visione dicotomica tra la fase della scelta del contraente e quella esecutiva. Sullo sfondo della funzionalizzazione del contratto alla realizzazione dell’interesse pubblico in concreto, oggi più che mai comprensivo dei fini ambientali, sociali e occupazionali, l’attenzione sarà posta in particolare sulla compresenza in entrambe le fasi di “momenti” (e quindi di regimi) pubblicistici e privatistici. A tal fine, l’attenzione sarà principalmente riservata, da un lato, all’estensione del regime delle trattative precontrattuali anche al momento che precede quello dell’aggiudicazione e, dall’altro lato, all’applicazione dello statuto pubblicistico all’esecuzione del contratto, specialmente in relazione all’esercizio del recesso, in ciò esprimendosi con maggior forza il senso dell’unitarietà fra le due fasi. Rilevata infine la frammentazione delle giurisdizioni, valorizzata l’esigenza di un giudice specializzato sulla materia e preso atto di alcune trasformazioni (potenziali e attuali) sul fronte più generale del riparto, si cercherà di fornire una lettura atta ad estendere, a Costituzione invariata, la giurisdizione esclusiva del giudice amministrativo su tutta l’unitaria vicenda contrattuale.

Tolerance optimization with statistical approach in the CAT environment

Nowadays, product development in all its phases plays a fundamental role in the industrial chain. The need for a company to compete at high levels, the need to be quick in responding to market demands and therefore to be able to engineer the product quickly and with a high level of quality, has led to the need to get involved in new more advanced methods/ processes. In recent years, we are moving away from the concept of 2D-based design and production and approaching the concept of Model Based Definition. By using this approach, increasingly complex systems turn out to be easier to deal with but above all cheaper in obtaining them. Thanks to the Model Based Definition it is possible to share data in a lean and simple way to the entire engineering and production chain of the product. The great advantage of this approach is precisely the uniqueness of the information. In this specific thesis work, this approach has been exploited in the context of tolerances with the aid of CAD / CAT software. Tolerance analysis or dimensional variation analysis is a way to understand how sources of variation in part size and assembly constraints propagate between parts and assemblies and how that range affects the ability of a project to meet its requirements. It is critically important to note how tolerance directly affects the cost and performance of products. Worst Case Analysis (WCA) and Statistical analysis (RSS) are the two principal methods in DVA. The thesis aims to show the advantages of using statistical dimensional analysis by creating and examining various case studies, using PTC CREO software for CAD modeling and CETOL 6σ for tolerance analysis. Moreover, it will be provided a comparison between manual and 3D analysis, focusing the attention to the information lost in the 1D case. The results obtained allow us to highlight the need to use this approach from the early stages of the product design cycle.
